Aston Martin DB2: A Comprehensive Guide

1. Introduction

The Aston Martin DB2, produced from 1950 to 1953, represents a crucial turning point in Aston Martin's history. Following David Brown's acquisition of the company in 1947, the DB2 was the first model to truly embody his vision of a high-performance, luxurious grand tourer. It signified a move away from pre-war engineering towards modern, sporting designs. The DB2 is unequivocally a grand tourer, designed for comfortable high-speed travel across long distances, blending performance with a refined driving experience. Its sleek lines, powerful engine (for its time), and luxurious appointments set the standard for future Aston Martin models and cemented its place in automotive history as a coveted classic.

2. Generations

The DB2, while relatively short-lived, saw a couple of key iterations that are important to distinguish.

  • DB2 (1950-1953): This is the original. Key features include:
    • W.O. Bentley designed 2.6-litre Lagonda straight-six engine.
    • Aluminium body construction.
    • Independent front suspension.
    • Live axle rear suspension.
    • Initially offered as a fixed-head coupe, but later a drophead coupe (convertible) became available.
    • Early examples had a split windscreen (two panes of glass), while later versions had a single-piece windscreen, which is arguably more desirable.
  • DB2/4 (1953-1957): Technically a different model, but a direct development of the DB2 and often considered part of the DB2 lineage. Key changes that distinguish it:
    • 2.9-litre version of the Lagonda straight-six engine.
    • Hinged hatchback, making it one of the earliest examples of a hatchback GT car.
    • Slightly modified bodywork to accommodate the hatchback and rear seats (small, but usable).
    • Visually almost identical from the front to the DB2, the rear is the giveaway.

3. Reliability & Common Issues

Owning a classic car like the Aston Martin DB2 requires a realistic understanding of its potential mechanical shortcomings. While beautifully engineered, these cars are over 70 years old, so wear and tear is inevitable. Regular maintenance and specialist knowledge are crucial.

Engine

The 2.6-litre (and later 2.9-litre) Lagonda straight-six engine is generally robust if properly maintained. However, expect the following:

  • Oil Leaks: A common issue in older engines. Check for leaks around the valve covers, crankshaft seals, and oil pan. Regular oil changes are vital, using a high-quality oil suitable for classic engines.
  • Carburetion: The original SU carburetors can be temperamental. They require regular tuning and rebuilds may be necessary. Upgrading to modern alternatives is possible, but detracts from originality.
  • Cooling System: Overheating can be a problem, especially in warmer climates. Ensure the radiator is clean and free of debris, and that the water pump is functioning correctly. Check for corrosion in the cooling system.
  • Valve Train: Listen for excessive valve noise, which could indicate wear in the valve train.

Transmission

The David Brown gearbox is generally reliable but can suffer from wear over time.

  • Gear Synchros: Worn synchros can make shifting difficult, especially into second gear. A gearbox rebuild may be necessary.
  • Clutch: Check the clutch for slippage or juddering. A new clutch may be required if it's heavily worn.

Suspension & Brakes

The suspension and braking systems are relatively simple but require regular maintenance.

  • Suspension Bushings: Check for worn suspension bushings, which can cause imprecise handling.
  • Brakes: The drum brakes require regular adjustment and inspection. Ensure the brake cylinders are not leaking and that the brake shoes are in good condition. Upgrading to front disc brakes is a common modification for improved stopping power.

Body & Chassis

The aluminium body is susceptible to corrosion, particularly around steel components.

  • Corrosion: Inspect the body carefully for signs of corrosion, especially around the wheel arches, sills, and door bottoms. Aluminium can corrode due to galvanic corrosion where it contacts steel.
  • Chassis: The chassis should be inspected for signs of rust and damage.
  • Panel Fit: Poor panel fit can indicate accident damage or previous repairs.

4. Driving Experience

Driving a DB2 is a truly unique experience. It's not about outright performance, but rather the feeling of driving a beautifully engineered classic car. While not blistering by modern standards, the DB2's straight-six provides ample torque and a satisfying exhaust note. The steering is direct (though heavy at low speeds), and the handling is surprisingly agile for its age. It's a car that rewards smooth driving and careful maintenance.

Pros:

  • Elegant and timeless design.
  • Characterful straight-six engine.
  • Rewarding driving experience.
  • Exclusivity and prestige.

Cons:

  • Requires regular maintenance and specialist knowledge.
  • Can be expensive to maintain and repair.
  • Drum brakes offer limited stopping power.
  • Not as comfortable or refined as modern cars.

5. Buying Advice

Buying a DB2 requires careful research and a thorough inspection. Here's some advice to help you make the right choice:

  • Condition is Key: Prioritize condition over originality. A well-maintained car is always a better investment than a "barn find" that requires extensive restoration.
  • Pre-Purchase Inspection: Have a qualified classic car mechanic or Aston Martin specialist inspect the car before you buy it. This is crucial to identify any potential problems.
  • Check the Paperwork: Verify the car's history and ownership. Look for evidence of regular maintenance and any previous repairs.
  • Originality vs. Usability: Decide how important originality is to you. Some modifications, such as front disc brakes or an improved cooling system, can enhance the driving experience without significantly detracting from the car's value.
  • Early vs. Late Models: The single-piece windscreen models (later production) are often preferred for better visibility.
  • DB2 vs. DB2/4: The DB2/4 offers slightly more practicality thanks to the hatchback, but the pure lines of the original DB2 are favored by some.
  • Market Values: Research current market values to ensure you're paying a fair price. Prices can vary significantly depending on condition, originality, and provenance.
  • Join a Club: Consider joining the Aston Martin Owners Club (AMOC). They can provide valuable advice and support to owners.

Years to look for: There's no single "best" year, as condition and history are more important than the year of manufacture. However, later production DB2s with the single-piece windscreen are generally more desirable.

What to avoid: Avoid cars with significant corrosion, unrepaired accident damage, or incomplete documentation. A poorly maintained car can quickly become a financial drain.

Buying an Aston Martin DB2 is a significant investment, but it's also a chance to own a piece of automotive history. With careful research and a thorough inspection, you can find a DB2 that will provide years of enjoyment.
